This indicates the power supply is ok.
Most often the cause of this would be the brake or clutch pedal switch.
Above the brake and clutch pedal there is a switch each. Check if the switches are closing fully when pedal is released. There should be a rubber stopper for pushing the switch pin, if it is worn or missing, the switch would not be working correctly. This would not allow the cruise control to work as the signal to the control unit is that either the clutch or brake pedal is being activated. Pin must be pushed in fully with minimal clearance, there must be clearance though.
Check it out and let me know if that is the cause.
